Abstract
Pyrrole and N-methyl pyrrole were copolymerized by ceric ammonium nitrate (CAN) in aqueous solution. The resulting products were characterized by Fourier-transform infrared spectroscopy, UV-visible spectroscopy, and four-point probe conductivity measurements. The specific electrical conductivity of the copolymers can be increased depending on the mole ratio of pyrrole/N-methylpyrrole. The conductivities of copolymers are in the range of 10-4-10-2 S cm-1. Kinetic parameters were obtained by gravimetric determination of the copolymer and found to be dependent on [pyrrole]0.87 [N-methyl pyrrole]0.06 [CAN]0.11 [H2SO4]1.28 from gravimetric determination.
